Door Lip Repair

04-23-2013, 06:59 PM

Greetings,

A small part of the lip that my door sits flush against has cracked and fallen away. I would like to repair the missing piece, as my door no longer starves the fire of oxygen(if i want) and i lose too much heat where i have a gap.

I have ordered Rutland's 2500 degree silicone sealant for wood stoves, but i am getting 2nd thoughts about whether the sealant is food safe.

Whatever I try, gravity is working against me as I probably have to put several small layers to prevent dripping.

I agree, I don't like your chances, but you can try wetting the area, wait 20 mins then paint the surface to be bonded to with a slurry of calcium aluminate cement and water then trowel castable refractory into the void.

Italians used to place the door in position and use wet newspaper jammed around the door to create a seal. This may work for you if the repair fails.
